BOOM-STICK AND METHOD OF PREPARING SAME.

Patented Mar. 30, 1920.

Application filed November 18, 1918. Serial No. 263,057.

To all whom it may concern:

Be it known that 1, JOHN G. ANDERSON, a citizen of the United States,residing at Pysht, in the county of Clallam and State of li ashington,have invented a new and useful Boom-Stick and Method of Preparing Same.

My invention relates to a new method ofpreparing logs for booming andtowing purposes, which consists in adjusting them to a boring mechanismwhile the logs are floating in Water so that a vertical bore is madenear the ends thereof and through the entire diameter of same, togetherwith a coun terbore of considerably larger diameter, adapted to receiveand securely hold a chain and toggle, for holding a series of logstogether for purposes above mentioned. Heretofore logs have beenprepared for these purposes by slow, laborious hand labor, and among theobjects of my invention is to achieve the desired result in a newer,quicker and better way, at a saving of labor and material.

I attain these objects by the method illustrated in the accompanyingdrawings, in which Figure 1 is a front elevation of a machine adapted tomake the bore and counterbore, in connection with a plan view of an endof a log prepared under my method.

Fig. 2 is a side plan of the ends of two logs prepared under my newmethod, and fastened together with chain and toggles.

Fig. 3, a top plan view of a log provided with a bore, and acounterbore.

Fig. 4, a side elevation of a boring mechanism and log float andcross-section of a log in position for boring.

Similar numerals refer to similar parts throughout the several views.

Various devices can be used for making the bore and counterbore, but adevice that I have found effective is illustrated in Fig. 1. It consistsof a framework to which the drill 2, of comparatively large diameter andposition for boring. 9, 9 and 10 and 10 gearing .to which power istransmitted by chains. 11, a float on which the boring mechanism ismounted. 18, log in position for boring, being held in place by chainand also the framework of the float. 14L, counterbore. 15, smaller bore.16, chain connecting toggles. 17 and 17 toggles connected to chain, andsaid toggles seated in the counterbores. 18, platform upon which anoperator stands for positioning the log and operating levers.

In preparing a log under this method, the log is floated underneath aprojecting side of the fioat until one end isproperly'positioned underthe large drill 2, the log being held in place by the chain 8, the drill2 then making the bore 14 as shown. The depth of this bore as shown inthe illustration is about one-third the thickness of the log, but thisdepth and its location from the end of the log varies according to thesize of the log to be prepared, the operator always having in view thatthere must be enough wood structure to give sufficient strength for thepurpose intended, the depth of the large bore in a small log beingconsiderably less than that in a large log. The log is then floated downto the smaller drill 3, it being held inpositon for boring by the chain8, when the smaller bore 15 is made. The log being floated on throughthe channel in the float the other end. is prepared in the same way, theresult being a log provided with a bore and a counterbore near each end,as shown in Fig. 3. Fig. 2 shows the ends of two logs prepared in thisnew way, the large bores 14 and 14: affording seats for the toggles 17and 17, the toggles being connected by the chain 16 passing through thesmaller bores. As is known to anyone skilled in the art, the old way ofconnecting a series of logs together for booming or towing purposes,consisted in chopping out with an ax a recess on the top and bottomportions of a log near the ends, or sloping of? the ends of a log withan ax until the thickness of the log at the ends was reduced to about 16inches, then boring holes therethrough adapted to connect logs thusprepared, with toggles and chains. This method as'will be p r eived, isvery slow and la orious, and.

sticks, in order to save chopping, the holes for the toggles are placedclose to the ends, and as the projecting piece which holds the chain andtoggle 1s ordinarily only about 16 inches thick, the boom sticks wouldfre-' quently break out at the ends, a serious matterin towing orbooming. By the new method the holes can be placed back from the endsany distance desired, without any extra trouble or labor. Regulatingthis distance by the size of the log, the boom sticks are prepared so itis practically impossible for the chain and toggles to breakout the woodstructure. .For instance, if the large bore is 16 inches back from theend, there is a length of 16 inches of the timber to withstand thestrain of the toggles and chain, on each end. This strain in towing andbooming of logs is sometimes very great.

I intend to make the apparatus described herein, the subject of anotherapplication.

I claim:

1. The method of connecting boom sticks end to end with chains of equallength having end toggles, which consists in forming a transverse borepartially through each stick, forming in axial alinement with said firstbores, second bores of greater diameter than said first bores andextending said second bores partially through the sticks so as to form,in conjunction with said first bores, shoulders, and passing the chainsthrough said first bores and seating said toggles upon said shoulders.

2. The combination of a plurality of boom sticks and chains forconnecting them, said boom sticks being provided at adjacent ends withtransverse bores extending therethrough and with other bores of greaterdiameter than said first bores to form in conjunction with said firstbores shoulders, said chains extending through said first bores andcarrying toggles at their ends seated upon said shoulders, said secondbores being of varying depth whereby boom sticks of different diametersare connected by chains of a uniform length.

JOHN G. ANDERSON.
